Mirrored symmetry mode changes?

[Tripod27]

Was something changed with the mirrored symmetry in the last few patches? I swear it used to always be lined up to face out of the hangar, and now it seems to always face in the direction the root part comes in

I used to be able to make rovers by using a bunch of I-beam parts one after the other to form the base, but since I have to turn the parts sideways to do this, I can't do it any more since the symmetry turns sideways as well, unless I place a different part as a root part and then build the entire rover as an attachment to that part and then change the root part and delete it

It also doesn't let you get different orientations on how it mirrors based on which way you turn the entire craft
